Title: Switching power supply system
Inventor: ISHII TAKUYA
IPC: H02M3/338
Filed: 1995-04-17
Abstract: PURPOSE: To provide a switching power supply system which is used in various kinds of electronic equipments, especially an RCC, and which operates stably even under a light load by preventing the increase in a switching frequency under a light load or rather actively lowering the frequency and thereby lessening a turn-on loss. CONSTITUTION: This system is provided with a controlling circuit 80. The controlling circuit 80 sets the minimum off-state time which would be longer as a load gets lighter based on a feedback signal from a detecting circuit 7. After the passage of the minimum off-state time, the controlling circuit 80 sees if the flyback voltage appears in a tertiary winding 23. If the controlling circuit 80 detects no flyback voltage in the tertiary winding 23, it turns a switching device 3 on and then determines the on-state time of the switching device based on the feedback signal of the detecting circuit 7 so that the output DC voltage may be stabilized. By providing such a controlling circuit in this system, a switching frequency gets lowered as a load gets lighter and then a turn-on loss can be lessened and thereby the system can operate stably even under a light load.

Title: Humidistat
Inventor: MATSUBARA MAMORU
IPC: B01D53/26
Filed: 1984-05-09
Abstract: PURPOSE:To increase the moisture absorbing capacity of a humidistat and to make it suitable for several purposes by allowing a water absorptive polymer to contact with a hygroscopic material and covering both with a moisture permeable material or contg. both in the vessel made of a moisture permeable material. CONSTITUTION:A polymer material which forms hydrous gel, such as a water absorbing agent derived from polyacrylic acid, is coated uniformly on a sheet of paper. Another sheet of paper coated with a hygroscopic material such as propylene glycol, glycerol, is heaped thereon. Further, the heaped sheets are held between two sheets of a moisture permeable material such as nonwoven fabric, and the periphery is heat-sealed to obtain thus a moisture conditioning sheet. The humidistat prepd. by this process absorbs moisture when the ambient humidity is higher than the equilibrium humidity but liberates moisture when the ambient moisture is lower than the equilibrium humidity, and keeps the ambient humidity at a constant value. The humidistat is useful for prevention of concrete wall from dew formation or for humidity control in a warehouse for foods.

Title: Shutter device of camera equipped with discrimination function of battery capacity
Inventor: SHIBATA ISAO
IPC: G03B9/08
Filed: 1980-07-04
Abstract: PURPOSE:To discriminate a battery capacity with a simple structure and to obtain a camera shutter device that can respond to said inspection by controlling a shutter release in responce to a state of an adsorption of an armature lever to a magnet for exposure control. CONSTITUTION:When a capacity of a battery is lowered, a state of an adsorption of an armature lever 80 to a magent (mg) for exposure control and a gap between the magnet and the lever 80 at an adsorption becomes large thereby allowing the  lever 80 to be turned counter clockwise. Thus, at shutter release a pin 82 of the  lever 80 falls in a concave part at a step part 33 of shutter release 30, and simultaneously, being slightly late, an extrusion part 82 of the lever 80 falls in a concave part  of a step part 34 of the lever 30, thereby allowing a detaining action to be interrupted. Further, before a lock of a shutter charge lever 40 is released and the shutter action is interrupted. Accordingly, with a simple structure, a battery capacity is discriminated and a camera shutter device that can respond to said result is  obtained, thus insignificant photographing when the battery capacity was lowerd is  prevented.
